2024 Tailings Report Feauture
Canary Systems is a provider of information systems that help to facilitate a better understanding of risk factors and short and long-term project performance.
International Water Power Magazine – Tailings Dam Monitoring
Canary Systems explains how it takes an integrated approach to data integration
and risk management when monitoring tailings dams.
International Water Power Magazine – Upgrading Dam Safety Systems
Canary Systems upgraded dam safety systems at the Rocky Mountain hydroelectric plant and the Kentucky lock and dam. It provided real-time monitoring and improved decision-making using automated data acquisition equipment, software, and comprehensive databases.
Engineering and Mining Journal Feature – Monitoring the Heap Leach Process
To help better understand the leaching process, what’s taking place inside the heap, and the stability of the pile, Canary Systems has designed a data collection and integration system, which includes rugged sensors, dataloggers, and MLSuite, a Web-based data suite, to capture and present the data in a useful
format.
International Mining Magazine Feature – Automated Data Acquisition
Canary Systems works directly with customers to integrate systems and extract valuable data from a plethora of monitoring instruments across mine sites, helping operators understand and manage risks in the process. Its remit covers instrumentation, system architecture, hardware and software,
and its own web-based data suite MLWeb.
Australian Mining Magazine Feature – Consolidating Mining Information
With 25 years under its belt, Canary Systems has established itself as a leading geo-monitoring solutions provider capable of connecting a mine site with a single data platform.
The American company can tailor its platform for any mining application, whether an operator is looking to store and analyse production or beacon data or interpret geologic mapping to understand underground or surface mining characteristics.
Web-Based Monitoring of Piezometers for the U.S. Army Corps of Engineers
The Moose Creek Dam, completed in 1979, is a 7.5-mile long earthen dam located in North Pole, Alaska designed to protect the Fairbanks and North Pole areas from flooding by regulating flow on the Chena River. The Corps of Engineers Alaska District tasked the Cold Regions Research and Engineering Laboratory (CRREL) to automate-groundwater levels measurement by installing 21 piezometers. CRREL added instrumentation and monitoring to a network system that aggregates all data. The web-based monitoring system provides a new tool that allows remote Corps personnel to monitor groundwater levels and seepage in areas of significant concern and receive notifications of developing distress during
a flooding event.
Understanding TDR Reflection Profiles
Time Domain Reflectometry (TDR) is a unique downhole deformation monitoring technique that can provide a cost-effective solution for the detection of subsurface deformation. TDR analyzes the changes in the electrical properties of a coaxial cable caused by deformation of the cable in a borehole when downhole movement occurs.
International Water Power Magazine Article – Monitor & Manage
Canary Systems aims to provide clients with turnkey solutions for their monitoring needs. Having the access to automated instrumentation data allows site personnel to make informed, risk management decisions and is a notable step in proper hydropower operation. This includes working directly with the hydropower site and personnel.
Structural response of a recycled thermoplastic lumber bridge under civilian and military loads
The U.S. Army Engineer Research and Development Center (ERDC) executed a load test and verification simulation on a novel thermoplastic composite bridge, T-8518, located on Tuckers Road in Camp Mackall, North Carolina. The bridge was made with 94% recycled plastic material, primarily recycled high-density polyethylene. An M1 Abrams battle tank and a loaded dump truck were used as a live load to determine the appropriate military load classification (MLC) and civilian load rating for the bridge superstructure. The bridge was designed to support the M1 Abrams battle tank with a gross weight of 63.5 tones to replace a dilapidated timber bridge that, because of its condition, was limited to a maximum load of 4.26 tones. A finite element analysis (FEA) of the entire superstructure based on the load test results indicated that the bridge exceeded design specifications and performed in a normal linear–elastic manner with relatively small viscoelastic responses for all loads.
Dam Safety Instrumentation Data Acquisition, Monitoring, and Data Visualization Improvements at the Rocky Mountain Hydroelectric Plant
Collection, organization, and presentation of instrumentation data can be a daunting task for dam owners. Historical data may be stored in multiple locations and formats, surveillance and monitoring programs may include numerous types of instruments with varying methods of data collection, instrumentation from different vendors may run on separate and often incompatible software, and dam safety instrumentation reporting is often time consuming. Dam owners such as Oglethorpe Power Corporation (OPC) have implemented improvements to their monitoring program utilizing new technology in data acquisition, database management and reporting. OPC’s Rocky Mountain Hydroelectric Plant surveillance and monitoring plan includes a combination of automated and manually read instruments that are synchronized into a single data management database platform. Integrated data management software allows OPC to quickly access charts and reports, set alarm notifications, and use templates to easily generate instrumentation reports.
Newburyport Pile Testing ASCE
As part of a research project investigating time dependent pile capacity gain, a heavily instrumented test pile cluster was installed at a bridge reconstruction site in Newbury, Massachusetts. The test pile cluster consisted of (i) three-instrumented test piles, (ii) a surrounding ground piezometer field, and (iii) a complex data acquisition array to monitor the instrumentation…
Gotthard Base Tunnel
The Gotthard base tunnel, which will begin operating in 2011, will be the most impressive element of the new transalpine railway line through the Swiss Alps.
In view of the difficult accessibility and extreme climatic conditions, ensuring the fast and reliable transit of more than 300 trains per day through the two 57 km long single-track galleries represents a considerable technical challenge.
This paper illustrates the process of translating the constraints and design specifications of this project into appropriate technical solutions which it then outlines…

Pont Ventoux TBM
This article describes the performances and the the problems recorded duringthe tunnelling with open HR-TBM of 13 km of the Pont Ventoux Hydroelectric Plant(Italy) and aims to put in evidence the factors that caused the excavation driving decreasing.As far as the main tunnel is concerned (F2) it is put in evidence the influence of the angle ofincidence between faults and direction of the excavation as a critical element in relation to the found problems.
Chickamauga Lock and Dam
The Tennessee Valley Authority completed construction of Chickamauga Lock and Dam in 1940. The U.S. Army Corps of Engineers designed the lock while TVA designed the remainder of the project…
Saluda Dam USSD
Saluda Dam Project is the largest ongoing seismic dam remediation project in the United States. Remediation includes construction of a new Dam directly at the toe of the existing earthen embankment built in the early 1930s.
Saluda Dam Intrumentation and Monitoring Program
Saluda Dam is owned and operated by South Carolina Electric and Gas Company (SCE&G). The Dam is located 8 miles upstream of the City of Columbia, South Carolina. Lake Murray, impounded by the Dam, has a storage capacity of more than 2,100,000 ac-ft of water.
Saluda Dam Then and Now
The Saluda Dam is currently being remediated to meet modern seismic safety requirements. An interesting aspect of the remediation is that it requires that Saluda Dam is built on the same site for the second time…
